Cautions and warnings
* Surge arresters must not be operated directly in power supply networks.
* Surge arresters may become hot in case of longer periods of current stress (danger of burning).
* Surge arresters may be used only within their specified values. In case of overload, the lead contacts may fail or the component may be destroyed.
* Damaged surge arresters must not be re-used.

Advantages Of The Surface Mount Ceramic Gas Discharge Tube 5.0x4.2mm 5DS
A gas- discharge tube is usually a glass tube with two electrodes
sealed through its walls. When a voltage is applied to the two
electrodes and the pressure of the gas in the tube is reduced,
eventually a pressure is reached at which a current flows, and the
gas begins to glow.
* Very high current-handling capability
* Low capacitance
* High insulation resistance
